    One-Way-Locking Ball Bearings

    Shielded

    Prevent shafts from reversing direction. These bearings have internal components (sprags) that lock against the outer ring to transmit torque one way but spin freely in the other. They're often found in backstopping, indexing, and overrunning applications. For example, they're used to prevent conveyors from reversing.
    Shielded—The balls are covered just enough to keep out large particles while allowing air to pass through and dissipate heat.
    Steel—Strong and wear resistant. However, these bearings are best for dry environments since moisture will cause them to rust.
    ABEC Rating—Bearings with an ABEC rating meet industry tolerance standards established by the Annular Bearing Engineers Committee (ABEC). They're rated on a scale from 1 to 9. The higher the rating, the tighter the tolerance. Bearings rated ABEC 1 or 3 are precise enough for most applications. If your application consistently runs at high speeds or requires high accuracy, consider bearings rated ABEC 5 or higher, since they generate less friction and heat.
